25832 - Statistics and Data Analysis
COMPETENCIAS/DESCRIPCION/OBJETIVOS
Lay the foundations of Descriptive Statistics and Probability Theory both from a theoretical and applied point of view.
Initiate the student in the Probability Calculus, useful for a latter design and analysis of theoretical statistical models, which
will act as a link between the data observed in a sample and what is unknown in the population. Probability will be
presented as an uncertainty measure. An appropriate methodology will be developed in order to extend the analysis of the
probabilities of some simple results obtained from a random experiment. These methods are based on mathematical
techniques and are themselves the basis of the procedures to be developed in other Statistics subjects to be taken in
further courses.
TEMARIO
I Descriptive statistics
1. Univariate statistical variables: plots and summary statistics.
Univariate statistical variables. Frequency distributions. Bar charts. Histogram. Frequency polygon. Pie chart. Simple and
weighted arithmetic mean. Median and quantiles. Mode. Variance. Standard deviation. Coefficient of variation. Range and
mean deviation. Box plot. Skewness. Kurtosis. Gini index. Lorenz curve. Centered and standardized variables. Effect of
linear transformations.
2. Bivariate statistical variables: plots and summary statistics.
Bivariate statistical variables. Frequency distributions. Marginal distributions. Conditional distributions. Scatter plot.
Covariance. Correlation coefficient. Statistics for linear combinations of statistical variables.
3. Index numbers.
Simple index numbers: properties. Average cumulative rate. Unweighted complex indices: simple arithmetic mean and
simple aggregative mean. Weighted complex indices: Laspeyres, Paasche, Fisher indices. Changes in the base period.
Deflation of statistical series: current and constant values. Applications.

Aclaraciones :
Teaching will be based upon formal lectures, practical lectures and seminars. Some seminars may take place at the
computer room.
Formal lectures will be about the theoretical contents of the subject. The applied lectures will include exercise solving and
examples illustrative of the theory.
EVALUACION
- Examen escrito a desarrollar
- Examen escrito tipo test
- Realizaci&oacute;n de pr&aacute;cticas (ejercicios, casos o problemas)
- Trabajos individuales
Aclaraciones :
1st exam round (January)
The student will choose one out of the two following evaluation systems:
1. A mixed evaluation based on exercises tried during the coursework and a written final examination. The final exam will
account for 70% of the full final qualification and the evaluation of coursework exercises (otherwise known as continuous
evaluation) will account for the remaining 30%. However, the student must obtain at least 4 points out of 10 in the Final
exam in order to get the marks from the continuous evaluation added to the final qualification. That is, any student not
achieving at least 4 points in the Final exam alone, will get a Fail as his/her final qualification, whatever the marks from the
continuous evaluation.
2. A full final examination for 100% of the final qualification.
Any student willing to choose the second system, and who will have his/her qualification drawn from the Final exam alone
(100%), must apply for it in a written form which can be obtained from the teacher and return it to the teacher within the
first four weeks of the course. Failure to do so implies that the student chooses the mixed evaluation system.
Any student not present in the Final exam official date and place will get an absent (No presentado) as qualification,
whatever election of evaluation system.
2nd exam round (June)
The qualification will be obtained solely (100%) from the corresponding Final examination, to be celebrated at the official
date and place.
